Totally agree.... Have seen YTube reviews between both units, 106 is slightly sharper images because of the pixels per sq inch. Very good point here. From what I have seen and read.... the main differences between the GT54 and GT56 is the 56 is larger and stronger Suppose to have more power increasing the overall range by 15 to 20 percent.
